IMPROVED APPARATUS FOR STRETHING SKINS. i

TO ALL WHOM IT MAY OONOERN:

Be Vit known that I, AUGUSTUS MARSH, of the city of Newark, in the county of Essex, and State of New4 Jersey, have invented an Apparatus for yStretching Raw -or Tanned Hides and Skins; and I do hereby declare the following to be a full and exact description of the same, reference being had to the drawings that accompany this'specication, and which make part of the same. v

The nature of my invention cdnsists in the construction of an expanding frame, consisting of bars that cross each other at the corners through double sockets, to which suitable screws and other machinery are attached, and also in adaptation of nippers to holding the skin in the stretching. j

Flat bars of wood, of suitable length, thickness, and Width to endure the strain required by the large or small size of hide or skin to be stretched, cross each other at their ends at right angles, through a socket having .two apertures at right angles to each other through it, the one above the other. A long screw passes through a, nut in a line parallel with the aperture, the nut being secured, one to cach aperture, in the socket. These screws are fast to theedges of the bars in bearings, in which they can turn, forcingu the socket along upon one' bar, carrying with it the other bar.

a a a a indicate the barsin the drawings. b b b b show the socket/s, one of which is shown enlarged in perspectve at Figure 2. c c e c show the screws, and d d dvd the nuts, fast to the sockets. The frame, Figure 1, A, is laid horizontally upon a table or upon trestles. A comm'on plain frame, B, is placed within A. -Nippcrs, having leather or other straps attached thereto, with holes `in the straps, are put upon the edges ofthe hide or skin, and attached t0 the bars a of the frame A byhooks, buttons, or inclined pins. By turning the screws the frame A is expanded and the leather stretched. The nippers and straps .are indicated by the letter e, and in perspective and enlarged in Figure 3. When desirable, in large frames, the two screws that carry one bar can be connected by belt or endless chain, that both ends may be moved equally by one crank, as the one.

crank,f, fits all the screws. The hide or skin being stretched can be fastened in any of the ordinary rnethods `to the common frame, B, and the nippers released to be again used. The nippers e are constructed with loops at the end of each arm.' The strap fast to one passes through the other, the strain closing thejaws upon the skin or hide.

I claim the frame A,'with the double sockets b, screws c, when constructed and` operated substantially as described'for the purpose of stretching raw or tanned hides or skins.

Also, the nippers and straps, in combination'with frame A, for attaching the skins or hides thereto forthe f t th' the ame. Purpose o s re C mg s AUGUSTUS MARSH.
